Resizable Cord Holder with Adjustable Arms and Retainer Mounts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions for preventing entanglements when unwinding cord bundles are inadequate, as they require the cord to be initially spooled on a specific device, limiting their functionality and effectiveness.
Innovation Solution
A resizable cord holder with adjustable arms and retainer mounts that can fit various cord bundle sizes, featuring elongated locking members and coil springs to securely store and unwind cord bundles without entanglement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a cord bundle is stored without a physical spool, then storage convenience is improved, but entanglement occurs during unwinding
Solution Approach 1:
The patent introduces a retainer mount as an intermediary device between the cord bundle and the user's hand. The retainer mount with C-shaped channel and retainer arm provides a physical structure that maintains the cord bundle's shape during storage and unwinding, preventing entanglement while allowing easy placement and removal without requiring the user to manually spool the cord around their forearm
2Reliability
If a fixed-size spool is used, then entanglement is prevented, but adaptability to different cord bundle sizes is reduced
Solution Approach 1:
The patent employs adjustable arms with multiple positioning holes that allow the retainer mount to be dynamically resized to accommodate different cord bundle dimensions. The arms can be extended or retracted and secured at various positions, enabling the same device to adapt to small, medium, and large cord bundles while maintaining effective retainer arm engagement to prevent entanglement
3Adaptability or versatility
If an adjustable cord holder is designed, then adaptability to different cord bundle sizes is improved, but device complexity increases
Solution Approach 1:
The patent divides the adjustable arms into modular components with discrete positioning holes at specific intervals. This segmentation allows the arms to be adjusted to predetermined positions using simple alignment and friction-fit mechanisms, avoiding the need for complex continuous adjustment mechanisms while still providing adaptability to different cord bundle sizes
Solution Approach 2:
The positioning holes and arm structure are designed to allow users to easily adjust and secure the arm positions through simple manual manipulation without requiring tools or complex locking mechanisms. The friction-fit design and ergonomic features enable self-adjustment, reducing the perceived complexity for the user

Function Achieved in This Case
The cord holder effectively prevents entanglements during unwinding by securely holding cord bundles of different sizes, allowing for easy storage and retrieval without the need for initial spooling on a specific device.
Implementation Method 1
a first retainer mount (4) positioned at a first end (13) of the first arm (1), a first coil spring (6) engaged to the first arm (1) and the first retainer mount (4), and a second retainer mount (5) positioned at a first end (13) of the second arm (2)

AI summary
A resizable cord holder for storing and unwinding cord bundles has two elongated C-channel arms connected adjacent to each other to form a supporting base. The arms are connected to each other by a handle, which is installed into corresponding handle holes in the two arms. The total length of the supporting base can be adjusted by reselecting which holes the handle is installed into. The supporting base can rotate relative to the handle for unwinding an installed cord bundle. Cord bundles are held in place by two retainer mounts at opposite ends of the supporting base. A separation member of the retainer mounts traverses through the arms, connecting a locking member and a retainer member on opposite sides of the arms, with the locking members within the C-channels. Coil springs around the separation members apply retaining tension to the locking members against the inner surface of the C-channels.
